What formation is NOT typically used by Marines?

The circle formation is not typically utilized by Marines in tactical situations. Marine formations are designed to enhance communication, control, and security during maneuvers, and each formation serves a specific purpose in terms of visibility, mobility, and the ability to respond to threats.

The column formation allows for compact movement through difficult terrain while keeping units in a position to maintain command and control. The wedge formation provides a balanced offensive capability, allowing Marines to cover more ground and engage potential threats while maintaining mutual support. The echelon formation enhances security and allows for a strong flank defense, facilitating effective movement toward a target. Each of these formations is structured to cater to combat operations, while the circle formation does not provide the necessary tactical advantages needed in military engagements and could limit visibility and defensive posture.
